---------------------------------------
Hi, [~andrewor14].
The dangling RDD seems to be removed.
For the following testcases, I can see both at the first. But, after refreshing Storage page
multiple times (about 1 minutes), `rdd2` is gone.
{code}
scala> val rdd1 = sc.parallelize(1 to 10000, 5000).setName("rdd1").cache()
rdd1: org.apache.spark.rdd.RDD[Int] = rdd1 ParallelCollectionRDD[0] at parallelize at <console>:24
scala> rdd1.count()
res0: Long = 10000
scala> sc.parallelize(1 to 10000, 5000).setName("rdd2").cache().count()
res1: Long = 10000
{code}
Maybe, not a bug?
